Red Bull Ampol Racing clinched its 11th teams' championship at the Boost Mobile Gold Coast 500.
The Holden squad secured the title with Shane van Gisbergen's victory in Race 32.
The team has an unassailable 683-point lead over Shell V-Power Racing Team with one round remaining.
The Banyo team needed a 576-point lead after Sunday to secure the title.
Triple Eight's cause wasn't helped when Broc Feeney crashed early on.
However, the margin was enough after the race to see the team clinch the championship.
It was further secured due to Anton De Pasquale's later disqualification.
Sunday's result was van Gisbergen's record-extending 21st win of the year, and fifth in a row.
Triple Eight first won the title in 2008, and reeled off seven in a row between 2010 and 2016.
It added wins in 2018 and 2021, and headed into 2022 as the defending champions.
The team clinched the title with a round to spare despite Feeney crashing out of Sunday's race.
Feeney was caught up in the lap 4 pile-up at the back chicane, and suffered his first DNF of the year.
